传统基坑变形监测工程中,数据处理过程往往仅注重对历史实测数据的简单计算,判断其变化是否超限,而对变形数据的内在变化规律及变形预测分析不足.针对这一问题,本文研究了不同变形模型在基坑变形监测数据处理中的应用,简述了回归分析模型、人工神经网络模型、灰色理论模型,并考虑了锚索轴力影响因素,对传统变形分析模型进行了一定的拓展和改进.结合某基坑工程,从实际应用角度分别对所列举的变形模型进行了分析比较,借助Matlab软件编程,对所述模型进行了程序实现.实验结果表明,考虑锚索轴力影响的改进模型拟合精度较高,适用于基坑变形监测数据处理.
Application of Deformation Model in Data Processing of Foundation Pit Deformation Monitoring
In the traditional foundation pit deformation monitoring engineering, the data processing process often only paid attention to the simple calculation of the historical measured data to judge whether its change exceeds the limit, but the internal change law of the deformation data and the deformation prediction analysis were insufficient. In view of this problem, this paper studied the application of different deformation models in the data processing of foundation pit deformation monitoring, briefly described the regression analysis model, artificial neural network model and grey theory model, and considered the influence factors of Anchor Cable axial force, so as to expanded and improved the traditional deformation analysis model. Combined with a foundation pit project, the listed deformation models were analyzed and compared from the perspective of practical application. With the help of MATLAB software, these model were programmed. The experimental results show that the improved model considering the influence of Anchor Cable axial force has high fitting accuracy. It was suitable for data processing of foundation pit deformation monitoring.
